help, x5 died
 

Well I just picked up an 01 X5 w/ 70k, and I love it. But driving home from work today it started chugging then died. When I got it home it had 8 codes
P0171 bank 1 too lean
P0174 bank 2 too lean
P1341 manufacurer control ingition system or missfire
P1343 "
P1351 "
P1345 "
P1353 "
P1347 "

Now I am a good mechanic but I have never worked on a BMW. If anybody has any thoughs on where to start that would be great!! My thoughts would be to check fuel pump, coils, vaccum leaks exc.
Thanks for the help, Chris
